The work done by any conservation force is reversible -explain.

Statement I : For a charged particle moving form point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connecting points P and Q. Statement II : The net work done by a conservative force on an object moving along a closed loop is zero.

Statement I: if work done by conservative force is negative then potential energy associated with that force should increase. Statement II: This is from the reaction Delta u =- W. Here Delta u is change in potential energy and W is work done by conservative force.

A rain drop of radius R falls from a height of H metre above the ground. The work done by the gravitational force is proportional to which one of the following?

Work done by magnetic force is zero. Explain.

Work done becomes zero

Work done in the reversible expansion is
